Yokomo YOKB7-S6AC Aeration shock cap, 4pcs  [YOKB7-S6AC]

Aeration shock cap overview

This is an RC-scale aeration shock cap sold as a set of 4pcs intended for use on dampers and shock assemblies in general RC applications. The part is described as an aeration or vented cap intended to manage airflow around the shock top, and to be used during routine maintenance and tuning of damper systems.

Installation is straightforward for anyone familiar with standard damper disassembly: remove the existing cap from the shock body after draining or supporting the oil as needed, place the vented cap on the shock shaft or body according to your damper layout, and reassemble. No special tools beyond typical shock service tools are required.

Tuning role: the vented cap provides a controlled path for trapped air and minor oil displacement during compression and rebound cycles, which can affect small changes in feel and rebound consistency. Use these caps as one part of a broader damper setup workflow—spring choice, oil weight, shaft condition and piston selection remain the primary tuning variables.

Compatibility notes: the product is listed as a general damper part; check physical fit with your shock body and shaft dimensions before installation. Because damper top dimensions vary across brands and chassis, confirm fitment on the bench prior to track use.
